The Multi Pass Oil Filter Test Rig is engineered for precise testing of hydraulic filter elements in compliance with ISO 4548-12 and ISO 16889 standards. These standards define procedures for assessing a filter's dirt holding capacity, filtration efficiency, and differential pressure characteristics.
In the multi-pass method, filters are challenged with test dust while online particle counters continuously measure downstream and upstream contamination levels. The rig integrates a fully automated system, controlled by PC software, providing real-time display of test parameters, data logging, and auto-generation of ISO-compliant reports.
Designed for filter manufacturers, R&D labs, and QA/QC teams, this system ensures repeatable, high-accuracy results for performance validation and production testing.
